Counterpoint.
Limpet controllers are currently a good way for one to determine the roll of a ship, i.e. "Hey, that guy has a hatchbreaker, he must be up to no good."
How does that shift if limpet controllers are suddenly universal?
(I am not saying that I disagree with the OP. I too have been in situations where I didn't have the right limpet controller to exploit an opportunity. But it would behoove us to think of all angles here...)
That is a valid point. However, I still think that having universal limpet controllers would benefit everyone and make gameplay more diverse, even if at some expense of cases like the one you point out.
When I saw that stranded ship out of fuel scenario in one of the reveal streams I though "that's cool, very star trekky". But also thought "who, except for the fuel rats, ever sacrifices a slot to carry around fuel transfer limpet controller just because?"...
Number of modules have grown quite a lot over the years, yet ship's slots have not, for the most cases. I'd hate to be pushed to have to fly large ships just to avoid being locked out of what should be "regular" content, like helping out a stranded ship.
